722. Present Imperative: The ending in 2d sing.

4. Present Imperative.

The ending in 2d sing. act., as being always preceded by a vowel, is हि hi (never धि dhi); and there are no examples of an omission of it. But this person is forbidden to be formed in the classical language from roots ending in a consonant; for both class-sign and ending is substituted the peculiar ending आन āná.
